When i use the OR condion in GQL it return error messege tht “BadQueryError: Parse Error: Expected no additional symbols at symbol OR . Why?

db.GqlQuery("Select * from vendor where access='public' OR organisation_id='"+ orgid +"'")

Answer 1

    GQL does not have an OR operator. However, it does have an IN operator, 
which provides a limited form of OR.

Docs clearly says that GQL doesn’t have an OR operator..

You could do something like this ..Make two queries and combine the results…

  vendors=vendor.all()
  pub_vendors = vendors.filter("access = ","public")
  vendors=vendor.all()
  org_vendors = vendors.filter("organisation_id = ",orgid)
  results = pub_vendors.extend(org_vendors)
